A supplement index built around how people actually stack.

Most supplement sites are either retailer storefronts or content farms. StackShop is neither. It's a curated index — a reference organized around the five supplement stacks that a meaningful number of people are actually running: longevity, GLP-1 support, sleep, performance, and gut health.

Each stack reflects a specific protocol — the set of compounds that researchers, clinicians, and high-information consumers have converged on for a given goal. The products in each stack are linked directly to the brand or an authorized retailer. There are no marketplace listings, no third-party sellers, no counterfeit risk.

Products are selected on the basis of evidence quality, formulation transparency, and brand credibility — not commission rate. Where a product has been independently tested or is backed by peer-reviewed clinical data, that's noted. Where it hasn't, that's also noted.

The process is straightforward. For each stack, we identify the compounds that have meaningful clinical backing or consistent presence in well-sourced protocols. We then find the best available product for each compound — prioritizing formulation quality, third-party testing, and direct-to-brand purchasing.

Every link on StackShop goes to the brand's own site or an authorized retailer. We don't link to grey-market listings or resellers. If a brand discontinues a product or changes their formula materially, we update or remove the listing.

We don't manufacture anything, hold inventory, or fulfill orders. StackShop is a reference and a starting point — you buy directly from the brand, with their return policy, their customer service, and their pricing.

StackShop earns a commission when you purchase through a link on this site. The commission is paid by the retailer or brand — it does not affect the price you pay.

This is disclosed on every page in the footer, and it applies to all outbound product links. We are required to disclose this under FTC regulations governing endorsements and testimonials (16 CFR Part 255), and we do so plainly: if you click a product link and make a purchase, we get paid.

Affiliate commission does not determine which products are included. A product with a 1% commission appears here if it's the best product for the stack. A product with a 40% commission is included for the same reason — or not included at all if it doesn't meet the bar. Commission rates are never shown to users and play no role in how products are ordered or presented.
